Donn talks about how to ease into remote working, tools for working remotely, tips and tricks for staying sane and productive while remote and he wraps it up by discussing the benefits employers have when hiring a remote workforce. Show Notes Remote work is best suited for information workers (programmers, designers, engineers, etc) Read Remote by DHH and Jason Fried Great book that echoes what I feel about working remote.

Remote day should be on Friday (fewer critical things happen on Friday, on average) After trial, if success, aim for 2-3 days of remote work. (Again, do this at the end of the week. Wed,Thu, Fri) Once successful, rally for full week of remote with an occasional in office visit (a day every week work two) Staying sane while working remote Do

Show Notes Effective Java (2nd Edition) - Joshua Bloch Obey the general contract when overriding equals When to not override equals: Each instance of the class is inherently unique. You don't care whether the class provides a "logical equality" test. A superclass has already overridden equals, and the superclass behavior is appropriate for this class. The equals method implement an equivalence relation which states it must be: Reflexive Symmetric Transitive Consistent For any non-null reference x, x.equals(null) must return false. A recipe for a high-quality equals method is as such:

If you've been an Android developer in the last 2 years, you must have seen this dreaded exception: dex: method ID not in [0, 0xffff]: 65536 Quick googling would immediately bring up the phrase "65K method count" and the recommended solution "multi-dexing".

In this mini Fragment, we introduce Joshua's seventh Item and a momentous end to the first chapter: Avoid finalizers Stay tuned for more items from our "Effective Java for Android developers" Fragment series. Show Notes Effective Java (2nd Edition) - Joshua Bloch Avoid finalizers If you don't know what they are, ignorance is bliss. If you know what they are, avoid them! Finalizers in Java != destructors in C++ (C++ counterparts to constructors). In C++ destructors you reclaim resources here (Java has GC) you also reclaim non-memory resources (use the try-finally block in Java) (unpredicatable amt of time between object becoming unreachable and finalizer being executed) Never do anything time critical in finalizer! System.gc + System.runFinalization increase chances - no guarantee System.runFinalizersOnExit + Runtime.runFinalizersOnExit are the ones that do - but they are fatally flawed Java 7 has try with resources, which is also interesting and auto-closeables. [Android] devs can only drea

Singer and Android developer Donn Felker explores Joshua Bloch's fourth Item: Enforce noninstantiability with a private constructor. Stay tuned, cause we got more of these quick ones coming. Effective Java (2nd Edition) - Joshua Bloch Enforce noninstantiability with a private constructor. Examples where you don't want class to be instantiated class that groups static methods and static fields (Util like classes think java.lang.Math/java.util.Arrays) class that groups static methods (including factory methods) for objects implementing specific interfaces (think java.util.Collections) class that group methods on a final class (vs. extending the class) Considerations Makes no sense to instantiate such "Util" classes Private constructors prevent instantiation Important side effect: prevents subclassing Contact us: @fragmentedcast [twitter.com] @donnfelker [twitter.com] @kaushikgopal [twitter.com]
